This invention relates to boxes,box blanks and methods of making the same and particularly to I wirebound boxes, box blanks and methods of making the same- I n It is an object of the invention to. provide certain improvements in the construction and manufacture of wirebound boxes of the type which are equipped with interengageable fasteners to permit a ready closing, opening and reclosing of 10 the box.

It is a further object of the invention to provide the wire bindings of a box with interengageable fasteners which are free from sharp projections.

It is a further object ofthe inventionto pro- 15 vide the wire bindings of a box with interengageable fasteners formed thereon without any intertwisting of the'wire ends and without driving the wire ends into the box parts. 4

It is a further object of the invention to provide 201- a wirebound box which is light in weight but strong and durable in construction. In the drawings: I Figure 1 is a perspective .view of a box blank embodying the invention and which when folded 25 constitutes the front, bottom, rear and top sections of the box.

Fig. 7 is similar to Fig. 1 but showing a'modifi form of securing the wire binding to the box parts.

Fig. 8 is a perspective view of a completed box e from the box blank shown in Fig. 7.

Ale-conducive to a better understanding of the invention it may be noted that heretofore interengageabie fasteners in the form of loops or bights have been provided on the ends of wires stapled to the box parts topermit a releasable connection by hooking the loop or bight on one box part through the loop or bight on an adjacent box rt. Prior to the present invention such loops as or bights have been formed on the binding wire ends in two different ways. According to one prior art practice the end of the wire was bent a distance from its end to provide the loop or bight and then the loop or bight was perpetuated by twisting the end of the wire about the bcdybf the wire. This practice is shown, for example, in

Patent No. 1,332,728 dated March 2, 1920. This practiceleft the sharp wire end exposed exteriorly of the box and this exposed wire end.fre quently caused injury to the person's-handling the box. This practice also required the use of a machine such as that shown in-said patent.

According to the other prior practice the wire was bent a distance from its end to form the loop or bight and then the loop or bight was perpetuated by driving the end of the wire into the box part. .This second prior practice is shown in patent to Rosenmund No. 1,933,030 of ctober'31, 1933.; While-this second practice of formingand perpetuating the loop or bight produced a highly satisfactory fastener by eliminating" the projecting wire end resulting from the first-mentioned practice, it necessitated the use of an expensive machine for forming the loops and driving the wire ends into the box parts. i

The present invention is intended to eliminate the objections to the two prior practices hereinbeforereferred to and to provide interengageable fasteners .for wirebound boxes free from sharp projecting ends and without performing the operation of driving wire ends into the box parts,

Referring to Fig. 6, the illustrative box oomprises a front section A,-a bottom section B, a rear section C, a top section D and two end sections E. The sections A, B, C and D each comprise side materlal i of veneer, resawed lumber or flbreboard and end cleats 2 preferably of resawed lumber.

Encircling the sections A, B, C and D are a plurality of pairs of flexible binders 3, preferably wires, which are secured to the side material by staples I which may straddle the pair of binders as shown in Figs. 1 and 6 or straddle each binder of a pair as shown in Figs. 7 and 8.

The ends of each pair of binders on the top section D are united to form a loop or-bight 5, and the ends of each pair of binders on the front section A are united-to form a loop or bight 6 which may be passed through the loop or bight and bent down against the front section of the box as shown in Fig. 6.

Referring to Figs. 4 and 5, end sections E comprise side' material I and one or more pairs of flexible binders 8 the ends of each pair being united to form loops or blghts 9. The ends E may also be provided with reeni'orcing battens ll stapled or otherwise secured to the side material 1. As shown in Fig. 6 the loops .or bights 8 on the ends E are passed through notches ll formed in the cleats 2 and bent to hold the end section in closed position.

The loops or bights 5 and 8 are preferably formed by integrating the ends of the pair of binders to produce a smooth loop or bight free of any projecting sharp ends. This may be done by welding the wire ends either before or after the binders are secured to the box parts or by preforming the binders in the form of an elongated loop as shown in Fig. 2.

The loops or bights 0 on the end sections may be similarly formed.

The box of this invention is preferably made by assembling in the flat the side material I and cleats 2 of the front, bottom, rear and top sections in foldable relationship and stapling the binding wires .3 thereto. The end sections are then connected to the under side of the blank as shown in Fig. 5 for shipment in the flat to the box user. To assemble the flat blank in Fig. 5 into box form the unattached side-of each end section is raised, the blank is folded into box form, and the other side of each end section is connected to an adjacent blank section by passing the loops or .bights 9 through grooves II to hold the end section in closing position.

When the box is fllled the top section D is lowered and bights 5 and 8 are interengaged'in the manner hereinbefore described to close the box.

The double strand arrangement of the flexible binders 3 increases the strength of the box as a whole and permits formation of the loops or bights I, O and 9 without any wire twisting operation and without any wire driving operation and produces an interengageable fastener free of any projecting wire end.

Because of the double strand arrangement of the flexible binders I and the added strength produced thereby, lighter wires may be used throughout the body of the. binder. When very light wires are used throughout the body of the binder the ends of the binder which are. united to form the loops or bights may be formed of heavier wire as shown in Fig. 3 to increase the holding power of the interengaged bights I5 and 8.

In Figs. 1, 4, 5 and 6 the staples straddle the two strands .of each pair of flexible binders. In Figs. 7 and 8 each strand is separately stapled to the side material, This latter arrangement may be preferable for shipments requiring a more rigid and less flexible box. With this arrangement the strands of each pair of binders may be more widely separated and thus produce wider loops or bights 6 and 6. A wider loop or bight furnishes greater resistance to relative shifting of adjacent sections than does a narrow loop or bight. Thus by varying the distance between the strands of each pair of flexible binders the flexibility or rigidity of the box may be varied.

It will be understood that the invention is not to be limited to the speciflc embodiment shown .for purposes of illustration as the inventive features may be variously embodied without departing from the invention.

It will also be understood that all of the features of the invention need not be used conjointly as they may be used to advantage in various combinations and subcombinations as defined in the subjolned claims.

I claim:

1. In a wirebound box, a flexible binder encircling the box and secured thereto and provided at its ends with interengageable fasteners, the flexible binder comprising a pair of strands integrally united at their ends to form a U-shaped bight free of sharp projections at each end of the flexible binder and the strands being separately secured to the box.

2. In a wirebound box, a flexible binder'en- Q circling the box and secured thereto and provided at its ends with interengageable fasteners, the flexible binder comprising a. pair of strands integrally united at their ends to form a U- shaped bight free of sharp projections at each end of the flexible binder.

3. In combination with a box part, a combined binder and fastener comprising a flexible metal loop elongated to provide substantially parallel strands with integrally united ends and secured to the box part to extend beyond an edge thereof for connection with another box part, the parallel strands intermediate their ends being of relatively light metal and at their ends being of relatively heavy metal.

4. In combination with a box part, a combined binder and fastener comprising a pair of flexible metal strands stapled .to .the box part and having their ends integrally united to provide substantially'a U-shaped bight free of sharp projections adapted to connect the box part with another box part.
